Mythal

Mythal is a powerful epic level magical effect, created by a circle of elven High Mages to protect and ward a large area with numerous powerful enchantments. They work by creating an area wherein the normal rules of magic no longer apply. A typical mythal prevents certain schools of magic from being employed while empowering others. It may restrict access to the warded area to certain classes of beings. For example, Silverymoon's mythal excludes evil dragons. Creation of a mythal sometimes requires the willing sacrifice of the lead caster's life, a result that lead to the first mythal's being named after its creator. In addition, many Mythal spells corrode over time, and if not maintained can become corrupted. This has occurred in Myth Drannor and resulted in the current state of that city.

While any epic magic "field or ward" can be considered a Mythal, scholars often use the following distinctions to describe various Mythals:

High Mythal or True Mythal

The first, great elven Mythals. Those Mythals created before the death of Mystryl, cast as 10th level spells.

Wizard Mythal

Those Mythals created later but with similar power and often by/including non-elves. Those Mythals created after the death of Mystryl, cast as 9th level spells, but considered in all aspects to be 10th level spells.

Near-Mythal

Others

Mechanical Mythal

Mythal type effects achieved through technology, and divine magic. Such systems are not subject to corruption.

In alphabetical order. Where a Mythal is known by more than one name or it's location is often used instaed of it's name, the mythal will appear multiple times with a "refer to" indicating it's "true" name
